How to play: Simply grab Unstoppable Surge Knuckles by his arms and legs and stretch them out. You'll be amazed at how far he can go - up to 3 times his size! Then let go, and watch him return to his normal shape. You can also squeeze him to feel his scrunchy texture. Notice: Keep this toy away from sharp objects as they could puncture it. Also, don't stretch it too hard or too often to avoid damaging the stretchy material. Maintenance: If the toy gets dirty, you can gently wipe it with a damp cloth. After that, let it dry completely before playing with it again. This toy is suitable for kids aged 4 and up, so make sure younger children are supervised when playing to prevent any choking hazards.
